Агроэкологическое состояния земель Томской области и перспективы применения методов дистанционного зондирования земли

Abstract

On base of studying the satellite images data received and processed at the space monitoring Center, Tomsk state University of control systems and Radioelectronics, and the results of ground agroenvironmental monitoring of arable land in Tomsk region performed by Federal state budgetary institution "Agrochemical service Station "Tomsk", revealed 39% of unused arable land, overgrown forest. From these investigations was find that the land used in agricultural production according to agro-chemical service, a decrease in soil fertility: decrease in organic matter content from 5 to 21%, increase in the proportion of acidic soils by 10 - 30%. The analysis of the main causes of negative trends in land use in Tomsk region was performed. The organizational and agro technical measures that increase the efficiency of use of arable land were developed. At the present stage is also required adaptation in the monitoring of agricultural land methods of Earth remote sensing, taking into account local soil and vegetation, and climatic conditions. There is a problem of integration of data with local ground measurements (and aircrafts) in order to bring them to a common spatial and temporal grid of satellite measurements, to construct dynamic models of seasonal cycles used to evaluate the observed changes of satellite data.
